Abstract

본 발명은 노래반주 시스템의 점수채점 장치에 관한 것으로, 노래반주 시스템으로부터의 반주음과 마이크를 통해 입력되는 사용자 음성신호가 LPF를 통해 각각 로우패스 필터링되고, A/D변환부를 통해 각각 디지털신호로 변환된 다음, 음정비교부, 음량비교부 및 음색비교부로 각각 제공되며, 음정비교부, 음량비교부 및 음색비교부를 통해 비교된 반주음의 음정, 음량, 음색과 사용자 음성신호의 음정, 음량, 음색의 차이에 의거하여 점수채점부에서 점수가 채점된 다음, 디스플레이부를 통해 노래반주 시스템의 모니터로 디스플레이되므로서써, 노래에 대한 점수가 음의 3용소에 기초하여 채점되므로, 보다 신뢰감 있고 고정밀한 점수채점을 수행할 수 있도록 한 것이다.The present invention relates to a scoring system for a song accompaniment system, wherein the accompaniment sound from a song accompaniment system and a user voice signal input through a microphone are low-pass filtered through an LPF, and respectively converted into digital signals through an A / D converter. After the conversion, it is provided as a pitch comparison unit, a volume comparison unit and a tone comparison unit, respectively, and the pitch, volume, tone and volume of the voice and the user's voice signal compared through the pitch comparison unit, the volume comparison unit and the tone comparison unit. The score is scored in the score scoring unit based on the difference in the tone, and then displayed on the monitor of the song accompaniment system through the display unit, so that the score for the song is scored based on the negative three places, so that the score is more reliable and accurate. This allows the scoring to be performed.
